As said back then, the original change looks a little suspicious,
and hence reverting it is certainly to be considered.

However, I don't see yet how this is connected to you having
a problem only with pinned vCPU-s.

But - with S3 working again (with the change here) or originally,
did you ever check whether post-resume Dom0 vCPU-s would
still be pinned? I suspect they aren't, and hence addressing the
crash may likely be achieved by properly restoring the pinning.
